New report details the top-grossing games in terms of digital earnings in 2015.

League of Legends was once again the highest-grossing digital game during 2015, according to a new report from research group SuperData.

With an estimated $1.628 billion revenue, Riot Games' MOBA leads the rest of the industry by a wide margin. Only three other games in SuperData's charts topped $1 billion in digital revenue for the year: two on PC that are big in Asia (CrossFire and Dungeon Fighter Online) and one on mobile (Clash of Clans). SuperData notes that League of Legends closed out the year with its highest-earning month ever.

Activision was the highest-grossing digital publisher for the full year.

"The top-ranking titles offer a market picture in which Activision currently dominates," SuperData's report states. "Earning the firm $2.9 billion in 2015, Activision controlled six of the 30 top spots across platforms, including the titles that came under its ownership following the acquisition of King Digital late last year. Supercell takes the number two position overall with $1.6 billion in earnings across its titles in the top 10."

PC games earned more ($32 billion) than those on mobile ($25 billion), but narrowing the totals to just the top ten games shows the two nearly tied. The top PC games accounted for $6.3 billion in sales, compared with $6.1 billion on mobile.

Overall, digital earnings were a record $61 billion on all platforms, an eight percent bump over 2014. Digital console game sales saw the biggest increase (34 percent), but made up just $4 billion for the year. Only the top three console games would have even cracked the top 10 on mobile.

The top tens for each category follow below; these are the top-grossing games in terms of digital earnings worldwide in 2015.
